Yes, one can restrict what commands get used. But one cannot
restrict what one does with that command.
For example, suppose I need a user who can move a file
to a backup area, and then create a new one using some editor
or other. I can "unleash" mv and the editor, but then
I cannot (AFAIK) prevent that user from using mv or the
editor on *any* file.

I can explain it for you, but I can't understand it for you.
I speak only for myself, and I am unanimous in that!
